well their range is 3200 which is about the same as NT-D Beam Magnums.

And Wave-rider is one ammo long reload while Zabanya's missiles are 2 shots with much more decent reload

unless Zabanya's missiles have crappy speed and tracking I'd be more afraid of 3600~7200 dmg of flying missiles coming after me than Zeta's crash. Especially since if Zeta misses it's crash (or is trying to use it's crash) it's gonna be within the reach of a rock's melee while Zabanya could be trolling behind some cover.
